Title: A coupling agent for reinforced plastics
IPC: C03C25/24
Filed: 1958-12-18
Abstract: Moulding compositions containing curable polymeric bonding agents and mineral fibre reinforcement materials or fillers such as glass, glass fibres or fabrics, glass wool, rock, rock wool or talc are improved in wet strength by pretreatment of the fibres or fillers with a cured oxidized synthetic drying oil made by air- or oxygen-blowing a polymer, or a copolymer with a conjugated diolefin having 4-6 C atoms, e.g. butadiene, dimethyl butadiene, isoprene, piperylene or methyl pentadiene, with an olefinic comonomer, e.g. styrene, para- or dimethyl styrene, acrylonitrile or methyl vinyl ketone, alone or mixed with a small proportion of a vinyl chlorsilane such as vinyl trichlorsilane, in a solvent, e.g. hydrocarbons, with or without an oxidation catalyst such as the naphthenate, octonate or oleate of cobalt, lead, iron or manganese.  The copolymerization catalyst may be a peroxide or metallic sodium.  The curable bonding agent may be the unoxidized polymer or copolymer referred to above or an unsaturated polyester resin.  In an example glass cloth is dipped in an acetone hydrocarbon solution of a butadiene-styrene copolymer containing 16% of oxygen, baked at 150 DEG C. and made into a laminate of 14 plies with a butadiene-styrene 80/20 copolymer containing methyl styrene and triallyl cyanurate, the laminate being cured at 280 DEG C. at atmospheric pressure.

Abstract: 1,170,847. Cranes. WARNOWWERFT WARNEMUNDE VEB. 14 Sept., 1967, No. 41896/67. Heading B8B. A ship's crane comprises a fixed gantry 10, Figs. 1 and 2, and a movable gantry 4 comprising a girder 4a and a column 4b pivotally mounted about a support 5, the gantry 4 being pivotable by traction ropes or cables 6a, 6b connected to the head of the column 4b, fixed deflecting means, e.g. pulleys 7a, 7b, for the ropes or cables being mounted on the gantry 10 on the angle bisectors between outermost pivoting positions and the vertical or substantially vertical position of the column 4b, whereby the position of the column support 5 can be changed by pivoting the column until it lies on one of the angle bisectors and engaging it by means of a releasable connection on the gantry 10 permiting rotation and longitudinal displacement of the column, the gantry 4 being moved to its new working position by releasing its support 5 and then using the ropes or cables 6a, 6b to move the latter. The gantry 4 has two columns 4b disposed adjacent two fixed gantries 10 and it can be moved between the positions P 1  and P 3 . The cables or ropes 6a, 6b extend from winches 9, or the pulleys 7a, 7b and pulleys 8 may be formed as winches. The columns are supported on rollers and are releasably locked at positions P 1 , P 3  by a pin, Fig. 9 (not shown). A crab 14 is supported on the girder 4a for pivotal movement about the longitudinal axis of the girder. The crab is suspended from a ring mounted on a travelling annulus and is moved by a rope drum on the annulus, the rope on the drum being connected at its ends to spring-loaded anchoring levers. The columns 4b are releasably connected to the gantries 10 by slidably engaging between side plates of the columns, Fig. 7 (not shown). In a second embodiment, Fig. 10 (not shown), the girder 4a is supported by only one column. The latter may be one of two separate supports 4d, 4e, Fig. 11 (not shown), or while providing a single column to take the bending from the girder 4a the other end of the latter may be also supported by another member, Fig. 12 (not shown). In a further embodiment, Fig. 14, load ropes 28 extend from winches 27 over rollers on the gantry 10 to a crane hook 29. Each rope 28 passes over a pulley at an end of the girder 4a to a pulley on the inside of the opposite column 4b, the pulleys being pivotable about horizontal axes. Where the ropes 28 cross over at the centre of the girder 4a the latter supports a guide pulley 30 to prevent chaffing of the ropes.

A method or apparatus for monitoring the flow of granular material (e.g. coal) in a conduit 4 comprises a source 5 projecting light via a polarizer 7 through a transparent inspection portion 3 of the conduit 4 and a light detecting system 10 receiving and monitoring light reflected by the material flowing through the conduit. The detector, preferably a photo-voltaic cell, should receive a continuously variable pulsed signal. An alarm is activated if the signal becomes constant for more than a certain period, thereby warning of blockages. The light source may be a laser, a white light source or a high intensity mercury vapour lamp. The light is best projected at an angle of 67 degrees to the surface of the material that is at an angle at which little or no surface reflection takes place from inspection portion 3. In an alternative system an alarm is activated when the rate of flow of material decreases below a certain value.
